Hey! Here you can find out how to adopt an actual wolf on The Sims 2 for PC. You CAN breed them with dogs, but I'm not sure about other wolves. I did this myself a few times so I know it works! (:

Steps

1

When you're in Neighborhood view, press Ctrl, Shift and C at the same time. This makes a bar pop up at the top of the screen.

2

In the bar, type 'boolProp testingcheatsenabled true' without the quotation marks, and hit enter.

3

Select the family which is going to adopt the wolf.

4

Turn off the free will. You can do this by going to 'options' then 'Game Options' and where it says 'Free Will', press 'off'.

5

Pick a Sim and make sure they're not doing anything. Shift-Click on the mailbox.

6

Press 'Make NPC' and go through the options until you find 'wolf'.

7

Click on it. Then wait a few seconds and a wolf should appear at the end of your lot. (NOTE: this does take a few minutes)

8

Greet the wolf. Then, find it in your relationship panel and drag both bars up to 100%.

9

Shift-click on the wolf and hit 'Make Selectable'. Then, find your Sim on the wolf's relationship panel and drag both bars up to 100% again.

10

Make your Sim stroke the wolf. This makes the Sim best friends with the wolf. (But, the wolf's relationship won't change yet). Then play with it, or something to build the relationship.

11

Shift-click the wolf and make it unselectable. Make sure it can leave (so there's no locked gates or doors) and it should leave.

12

Wait for the wolf to leave, then shift-click the mailbox and bring it back. It might be the wrong wolf, so repeat until it's the right one.

13

Click the wolf again. It should say 'Adopt' under the actions you can do. If it doesn't, play with the wolf, make it leave and come back. But it SHOULD say 'Adopt' first time.

14

There should be a dialogue box that comes up, saying '(wolf's name) has become quite attached to (Sim's name). Do you want to adopt this pet?' or something. Press 'Yes' or 'OK' (I can't remember exactly, sorry) and you have a pet wolf (:
